839674-89-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 839674-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,9,6,7 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 839674-89:
(8*8)+(7*3)+(6*9)+(5*6)+(4*7)+(3*4)+(2*8)+(1*9)=234
234 % 10 = 4
So 839674-89-4 is a valid CAS Registry Number.

Efficient synthesis of various acycloalkenyl derivatives of pyrimidine using cross-metathesis and Pd(0) methodologies

Amblard, Franck,Nolan, Steven P.,Schinazi, Raymond F.,Agrofoglio, Luigi A.

, p. 537 - 544 (2007/10/03)

Novel acyclonucleosides (9a-d, 10a-d, 18a,b and 19a,b) have been prepared using Pd(0) and cross-metathesis methodologies. The allylic N-alkylation under Tsuji-Trost conditions was used to introduce the nucleobase, while the Suzuki-Miyaura reaction afforded C-5 substituted uracil analogues. The cross-metathesis performed with a ruthenium catalyst was used to provide new acycloalkenyl nucleosides. The antiviral activities of all final compounds have been evaluated.
